Single Wire/Cable Vertical Flammability Test Apparatus (Model: DZ-3)
1. Introduction
Single wire vertical flammability test apparatus is designed according to IEC60332-1, GB/T18380.11, GB/T5169.14. It adopts bunsen burner and certain combustion gas, and the burning rate, after glow time, after flame time and damage length of the specimen evaluate the fire hazard. The test apparatus is applied to evaluate the flame retardancy of single cable or wire with diameter more than 8mm or less than 8mm. It is suitable for R&D, QC departments of the industries of lighting appliance, LV appliance, household appliance, motor and etc..
